Authorities say a South Carolina man's good intentions almost caused an explosive situation.

After the man's uncle died, he discovered that his relative had collected potentially explosive materials including grenades, dynamite and black powder.

The man, who was not identified by police, feared the materials might fall into the wrong hands, so he drove 80 miles to his uncle's house and loaded his truck with some of the items. Then he drove back to his home county of Union on Wednesday to give the materials to police.
